I would like to deflect a 125 KHz ultrasound pulse by 90 degree under
water
in the simplest possible way.
If I used a plate of material at 45 degrees to the beam how can I ensure
that as much energy as possible is deflected and not either absorbed by
the
material or passed straight through?
Do I simply choose a material with as higher density as possible or does
the
density not matter ?
Do I just need an acoustically stiff material, and if so what ?
Any help would be much appreciated.
